# Monta o Rogue Janitor (Lauren Hall, 7DRL 2019, MIT) a partir do commit 8bf1f80 de github.com/laurheth/rogue-janitor, sem etapa
# de build do autor. Mudancas em rogue-janitor/no-external.patch: o rot.js 2.0.3 (BSD-3) deixa de vir do jsDelivr e
# vai junto, pelo mesmo arquivo do npm (sha256 conferido), e a fonte Share Tech Mono do Google Fonts, que o jogo
# nunca usava (o ROT.Display usa monospace), sai.
# O index.html ganha tambem <meta charset="utf-8">: sem ele o navegador le o texto UTF-8 como Latin-1.
#
#   src/FredGames.Bundler/Builds/build-rogue-janitor.sh
#
# Saida: artifacts/build/rogue-janitor-8bf1f80/rogue-janitor-8bf1f80-dist.tar.gz (pasta dist/; igual em dois builds seguidos).
